Getting the Current Time

     

This section shows the way of getting  the current time of the system.

In this section, through the given program you can get the current time in the proper format (Hour:Minute:Second AM/PM). This program shows the current time by using the various methods of the Calendar class. These are explained as follows:

Code Description:

Calendar:
Date is the special instance of the time. This class helps you to convert a date format object into the integer fields like YEAR, MONTH, HOUR, MINUTE, SECOND etc.

Calendar.get(Calendar.MINUTE):
Above method gives you the minute value from the current time and MINUTE is the predefined field of the Calendar class which returns the integer value i.e. the minute value of the current time

Calendar.AM_PM:
Above field of the Calendar class returns the integer value 1, if the current time is in the PM otherwise it returns 0 value which denotes the time is in the AM period.

Here is the code of the program:

import java.util.*;

public class CurrentTime{
  public static void main(String[] args){
  Calendar calendar = new GregorianCalendar();
  String am_pm;
  int hour = calendar.get(Calendar.HOUR);
  int minute = calendar.get(Calendar.MINUTE);
  int second = calendar.get(Calendar.SECOND);
  if(calendar.get(Calendar.AM_PM== 0)
  am_pm = "AM";
  else
  am_pm = "PM";
  System.out.println("Current Time : " + hour + ":" 
+ minute + ":" + second + " " + am_pm);
  }
}

Hi! I added this line: int month = calendar.get(Calendar.MONTH); and what I got was one month less than the actual month. Why is it so?
